CSV en JSON

Convertissez du CSV en JSON.

Paste CSV to convert it to JSON. With the header-row option, the first row becomes the object keys; otherwise you get an array of arrays. Quoted fields and commas are handled. Everything runs locally in your browser.

Votre saisie est traitée localement dans votre navigateur — rien n'est envoyé, stocké ni journalisé.

Questions fréquentes

Is my text sent to a server?

No. Everything runs locally in your browser — your text is never uploaded, stored or logged.

Are quoted fields supported?

Yes — fields wrapped in double quotes (including commas and escaped quotes inside them) are parsed correctly.

What does the header option do?

On: the first row becomes the keys for each JSON object. Off: each row becomes an array of strings.

Is it really free?

Yes — free, with no signup and no limits.
